How does Goitre Iodine deficiency affect the body?

Answer 1

The thyroid gland produces thyroxine and triiodothyronine which essential element is iodine. It order for these hormones to function they need iodine. Without these hormones the thyroid can not function properly and swells (goiter). Reduced function in the thyroid also caused the hypothalamus and pituitary gland to produce thyroid stimulating hormone which irritates the thyroid more.

Answer 2

Iodine is necessary for making thyroid hormone. If it is deficient you will not make the hormone and in response the thyroid gland will swell causing a lump in the front of the neck known as a goiter.

Symptoms of low thyroid include weight gain, fluid retention, cold intolerance, fatigue, muscle weakness, constipation and others.

Answer 3

The body does not make iodine on it's own, and you must consume iodine. An iodine deficiency can cause problems with the thyroid including goiter, which is an enlargement of the thyroid gland.

Answer 4

Iodine is used to produce the hormones thyroxin and tri-iodothyroxin in the thyroid. With iodine deficiency the body can no longer produce these hormones. These hormones are controlled by negative feedback, meaning that these hormones decrease their own production in the thryoid. So without thyroxin and tri-iodothyroxin there is no longer a signal to stop production by the thyroid and therefore the thyroid goes into overdrive while the body loses its thyroid hormones. This results in a goiter(enlargment of thyroid) and HYPOthyroidism(look up symptoms on wikipedia). Iodine deficiency is extremely rare in all developed nations because we add iodine to salt.

Answer 5

Iodine deficiency can cause a goiter, an enlargement of the thyroid gland.
